CN205943716U - Parallel reactor with coiling of all insulation transposition aluminum conductor - Google Patents

Abstract

The utility model provides a parallel reactor with coiling of all insulation transposition aluminum conductor, including the reactor solenoid, winding wire on the reactor solenoid comprises stranded small bore monofilament aluminum wire, and the cross section is merged into to stranded small bore monofilament aluminum wire for the light -duty winding wire of flat and wide shape, winding wire carries out the high density transposition between each strand, makes winding package all interior parallel winding lines merge into a branch road. This kind of parallel reactor with coiling of all insulation transposition aluminum conductor reduces the parallel branch number of reactor winding greatly to imitate the stream loss and the harmonic impedance that reduce the reactor.

Description

A kind of shunt reactor of use all insulation transposition aluminum conductor coiling

Technical field

The utility model is related to the reactor in a kind of power industry, and more particularly to one kind all insulation replaces The shunt reactor of aluminum conductor coiling.

Background technology

China's power grid construction, enlarging and transformation deepen continuously at present, although traditional dry type hollow shunt reactor should With extensive, but there is also obvious defect, particularly eddy-current loss harmony wave impedance is larger, and layer insulation poor performance, thus draw The accident rate rising is also high, has a strong impact on the safe operation of electrical network, and reactor volume floor space is larger.

Content of the invention

The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, provides one kind all insulation transposition aluminum conductor The shunt reactor of coiling.

The purpose of this utility model to solve by the following technical programs：One kind all insulation transposition aluminum conductor coiling Shunt reactor, including reactor line bag, the winding wire that described reactor line is wrapped is made up of multiply small bore monofilament aluminum steel, The light-duty winding wire that cross section is flat and wide shape merged into by multiply small bore monofilament aluminum steel, and winding wire is carried out between each stock High density replaces, and makes all parallel winding lines in a winding bag be merged into a branch road.

In such scheme, in coiling front surface wrapping insulating barrier, after transposition merges, wrapping is exhausted for described small bore monofilament aluminum steel Edge layer, the winding wire being merged into surface impregnation in winding process.

In such scheme, described small bore monofilament aluminum steel helically coiling side by side, adjacent two row's rotary orientations are contrary.

In such scheme, interior one layer of setting of described reactor line bag is encapsulated without the false of winding wire, reactor line bag Encapsulating between using polyester glass fiber leading-drawing rod as axially radiating airway support.

Compared with prior art, it is beneficial for a kind of shunt reactor of the utility model use all insulation transposition aluminum conductor coiling Effect is：

1. winding wire carries out high density transposition between each stock, so that all parallel winding lines in a winding bag is merged into One branch road, greatly reduces the parallel branch number of reactor winding, thus imitating the harmonious wave impedance of stream loss reducing reactor.

2. the use of all insulation transposition aluminum conductor, and the gum dipping process in winding process, reduce reactor interlayer and Turn-to-turn insulation risk, strengthens interlayer and turn-to-turn voltage endurance capability, and wire overall mechanical strength can be made to greatly increase.

3. floor space reduces, and can meet the power transmission and transformation place that installing space is required.

Specific embodiment

Below in conjunction with the accompanying drawings the shunt reactor of the utility model all insulation transposition aluminum conductor coiling is done detailed further Thin description：

Fig. 1 is a kind of structural representation of the shunt reactor of the utility model use all insulation transposition aluminum conductor coiling, Fig. 2 It is the top view of Fig. 1, Fig. 3 is the coiling schematic diagram of winding wire, Fig. 4 is the cross sectional enlarged view of Fig. 3.In figure, this uses entirely exhausted The shunt reactor of edge transposition aluminum conductor coiling, including reactor line bag 1, the winding wire on reactor line bag 1 is by little section of multiply Face monofilament aluminum steel composition, winding wire carries out high density transposition between each stock, makes all parallel winding lines in a winding bag It is merged into a branch road.The false encapsulating 2 without winding wire for the interior one layer of setting of reactor line bag 1, the encapsulating of reactor line bag 1 Between using polyester glass fiber leading-drawing rod 3 as the air flue 4 that axially radiates support.

Multiply small bore monofilament aluminum steel 6 merges into the light-duty winding wire 5 that cross section is flat and wide shape, small bore monofilament Aluminum steel 6 wrapping insulating barrier after coiling front surface wrapping insulating barrier, transposition merging, the winding wire 5 being merged into is in winding process Surface impregnation.Small bore monofilament aluminum steel 6 helically coiling side by side, adjacent two row's rotary orientations are contrary.

This shunt reactor with all insulation transposition aluminum conductor coiling greatly reduces the parallel branch number of reactor winding, Thus imitating the harmonious wave impedance of stream loss reducing reactor, reducing reactor interlayer and turn-to-turn insulation risk, strengthening interlayer And turn-to-turn voltage endurance capability, and wire overall mechanical strength can be made to greatly increase.

The above, be only preferred embodiment of the present utility model, not the utility model is made any formal Restriction although the utility model is disclosed above with preferred embodiment, but be not limited to the utility model, any ripe Know professional and technical personnel, in the range of without departing from technical solutions of the utility model, when available the disclosure above method and Technology contents make a little change or the Equivalent embodiments being modified to equivalent variations, as long as being without departing from the utility model technology The content of scheme, any simple modification above example made according to technical spirit of the present utility model, equivalent variations with Modify, still fall within the range of technical solutions of the utility model.
